Winter can bring cosy family days, school activities, and holiday gatherings, but it is also a time when children catch more colds and respiratory infections. Spending more time indoors and being around classmates can make it easier for germs to spread. Common illnesses include colds, influenza, RSV, and COVID-19. While parents cannot prevent every infection, simple daily habits can lower the risk and help children stay healthier throughout the season. A little preparation, regular hygiene, and guidance from your paediatrician can make winter easier for the whole family.
Keep Your Child’s Vaccinations Up to Date
Vaccination is one of the best ways to protect children from certain serious seasonal infections. The annual flu vaccine helps reduce the risk of influenza and its complications. Depending on a child’s age, medical history, and current recommendations, other immunisations may also protect against respiratory illnesses. The Centres for Disease Control and Prevention (CDC) recommends seasonal flu vaccination for people six months and older in the United States, with rare exceptions. Children under five, particularly those younger than two, and children with certain long-term health conditions may face a greater risk of serious flu complications.
Parents should review their child’s vaccination record with a healthcare professional and ask which immunisations are recommended. Infants may have additional RSV protection options, depending on their age, health history, and maternal vaccination history. A visit to a pediatric office in Las Vegas can help parents review their child’s vaccination needs and discuss questions about seasonal illness prevention.
Teach Children to Wash Their Hands Properly
Children touch many things throughout the day, including classroom supplies, toys, playground equipment, desks, and shared surfaces. They may then touch their eyes, nose, or mouth without realising it. This creates opportunities for germs to enter the body. Handwashing is a simple habit that can reduce the spread of many infections. Encourage children to wash their hands with soap and clean running water before eating, after using the bathroom, after playing outside, and after coughing, sneezing, or blowing their nose.
Teach them to scrub all parts of their hands, including between the fingers and around the nails, for at least 20 seconds. Younger children may enjoy singing a short song while washing to help them remember how long to scrub. When soap and water aren’t available, an appropriate hand sanitiser can help. Parents should supervise young children when using sanitiser and store it safely out of reach. The CDC’s healthy habits for preventing flu offer practical advice on hand hygiene and other everyday ways to reduce germ spread.
Encourage Healthy Eating and Regular Hydration
A balanced diet supports normal growth and helps children’s bodies function properly. During winter, busy school schedules and holiday routines can sometimes lead to skipped meals or too many convenience foods. Parents can help by keeping regular meal and snack times and offering a variety of nutritious choices.
Include fruits, vegetables, whole grains, protein sources, and calcium-rich foods in your child’s meals. Oranges, berries, leafy greens, carrots, eggs, beans, yoghurt, and whole-grain foods are examples of ingredients that can form part of a balanced diet. No single food can prevent a cold or guarantee that a child will not get sick. Be cautious about supplements or products advertised as immune boosters. Children usually get the nutrients they need from a varied diet, and supplements should be used only when appropriate for their individual needs.
Water should remain the main everyday drink for most children. Offer water regularly, especially after physical activity or when indoor heating makes the air feel dry. Children who have a fever, vomiting, or diarrhoea may need extra attention to fluid intake. Parents who have concerns about picky eating, poor appetite, or nutrition can discuss them during a visit to a pediatric office in Las Vegas.
Make Sleep a Daily Priority
Children need enough sleep to support their physical health, learning, mood, and development. When school, family events, and holiday activities disrupt bedtime, children may become tired and have a harder time managing their daily routines. Try to keep a consistent bedtime and wake-up time, including on weekends when possible. A calming bedtime routine can help children settle down. Reading a story, taking a warm bath, or listening to quiet music may help younger children relax.
Limit screen use before bedtime, since phones, tablets, televisions, and video games can make it harder for some children to settle. Keep bedrooms comfortable and create a quiet sleeping environment. Sleep needs vary by age. Babies, preschoolers, school-age children, and teenagers all require different amounts of rest. If your child regularly has trouble falling asleep, snores heavily, or seems unusually tired during the day, ask your paediatrician for advice. Good sleep does not guarantee that a child will avoid seasonal illnesses, but it is part of the daily care that supports healthy development.
Keep Sick Children Home and Reduce the Spread of Germs
Children often want to attend school, sports, or family gatherings even when they feel unwell. Parents may face pressure to maintain normal schedules, but sending a sick child into a group setting can spread infections to classmates, teachers, and other families. Watch for symptoms such as fever, coughing, a runny nose, sore throat, unusual tiredness, or stomach problems. If your child is unwell, allow time for rest and follow the school’s illness policy.
For common respiratory viruses, CDC guidance says people can generally return to normal activities when their symptoms have been improving overall, and they have been fever-free for at least 24 hours without using fever-reducing medication. Extra precautions for the next five days can help reduce the chance of spreading illness.
For more information, read the CDC’s guidance on preventing the spread of respiratory viruses when sick. At home, avoid sharing cups, utensils, and towels while someone is ill. Clean frequently touched surfaces, such as door handles, light switches, and commonly used devices. These habits can help protect other family members.
Improve Indoor Air and Practice Good Cough Etiquette
Cold weather often means children spend more time indoors. Classrooms, childcare centres, and family homes can bring people into close contact, giving respiratory viruses more opportunities to spread. When weather and outdoor conditions allow, open windows or doors briefly to improve airflow, and make sure heating and ventilation systems are maintained according to their instructions. A suitable air cleaner may provide another layer of support in some indoor spaces.
Teach children to cough or sneeze into a tissue or the inside of their elbow rather than their hands. Throw used tissues in the trash, then wash your hands. During periods when respiratory illnesses are spreading, families can take extra precautions in crowded indoor settings. A well-fitting mask may help in certain situations, especially when someone is sick or around people at higher risk of severe illness. The CDC’s respiratory illness prevention guidance explains how cleaner air, hygiene, and staying home when sick can work together to reduce infection risks.
Keep Children Active and Maintain Healthy Daily Habits
Winter weather can make outdoor play less appealing, but children still benefit from regular movement. Physical activity supports healthy development, sleep, mood, and general well-being. Encourage age-appropriate activities such as dancing, indoor games, stretching, supervised play, or outdoor walks when conditions are comfortable. Children do not need expensive equipment or organised activities to stay active.
Dress children appropriately for outdoor temperatures and make sure younger children are supervised. In colder conditions, use suitable layers, warm footwear, hats, and gloves. Change wet clothing when needed, and bring children indoors if they become uncomfortably cold. Try to keep family routines steady during school breaks and busy periods. Regular meals, enough sleep, movement, and time to relax all contribute to children’s overall health.
When Should Parents Contact a Paediatrician?
Most childhood colds and mild respiratory infections improve with time and supportive care. However, some symptoms need medical attention. Contact your child’s healthcare professional if symptoms are getting worse, a fever persists, your child is not drinking enough, or you have concerns about their recovery.
Seek urgent medical care if your child has difficulty breathing, bluish lips or face, ribs pulling in with each breath, signs of severe dehydration, unusual difficulty waking, or a seizure. Any fever of 100.4°F (38°C) or higher in an infant younger than three months requires immediate medical evaluation. The CDC provides a fuller list of respiratory illness symptoms and emergency warning signs in children.
